• Positive (two variables rise or fall together)
• Zero correlation is when there is no relationship between the variables

Question 2

What are three strengths of Correlations?

Answer 2

-A useful preliminary tool for research, asses strength and direction of a relationship, they provide a precise and quantifiable measure of how 2 variables are related. Suggest ideas for possible reasearch?
- used as a starting point to access possible patterns before committing to a study.
- Quick and economical as no controlled environment/ manipulation of variables needed. Secondary data can be used, less time-consuming.

Question 3

What are three limitations of Correlations?

Answer 3

• Only tells us how variables relate and not why, cannot demonstrate cause and effect or establish the direction of effect
